I’m struggling with stable end-to-end connectivity with srsRAN LTE implementation. I’m using LimeSDR-mini as RF frontend for both enb and ue. Every time after successful connection, ping works between epc and ue for 2/3 minutes. After that enb unable to establish connection with ue and reattach failed. Also tried with cots-ue and noticed similar results.
I already opened an issue on srsRAN github two weeks before. No response so far. I’ve tried with different n_prb, bandwidth, tx_gain, antenna, dl_earfcn.
Found UE for Downlink Notification MME Ctr TEID 0x1, IMSI: 901700000048363 T3413 expired -- Could not page the ue. Received GTP-C PDU. Message type: GTPC_MSG_TYPE_DOWNLINK_DATA_NOTIFICATION_FAILURE_INDICATION Found UE for Downlink Notification MME Ctr TEID 0x1, IMSI: 901700000048363 T3413 expired -- Could not page the ue.
Has anyone here using limesdr-mini encountered this error messages ? Could you please share some ideas.
